Natural gas hydrate (NGH) holds great promise as a source of clean energy. It is critical for acquiring the largest possible in situ NGH core eigen features and resource assessment. However, existing coring technology has limitations, such temperature increments, limited diameters, low rates, complex structures. Therefore, this study designs proposes an freezing (NGHFC) method verifies capacities NGHFC laboratories experimental wells. Results suggest that shows good heat-retention...
Variability in food availability leads to condition-dependent investments reproduction. This study is aimed at understanding the metabolic response and regulatory mechanism of female
To investigate the embryonic development of mud crab Scylla paramamosain , we analyzed three critical parameters: egg color of, embryo morphology (through conventional and laser scanning confocal microscopy), distribution cell divisions. During development, exhibited a progressive transition, shifting from orange to reddish-orange, then brown, before ultimately darkening black. Each displayed spherical shape, measuring approximately 280 μm in diameter, characterized by smooth surface devoid...
It is of great significance to promote the quantitative research soil science and implementation precision agriculture. On this basis, taking Xuwen County as object, paper comprehensively analyzed characteristics cultivated land in clarify nutrient content spatial distribution County, applied methods geostatistics, geographic information system (GIS) fuzzy mathematics, referred quality grade standard (GB/T 33469-2016), analyze evaluate fertility region. The results show that optimal...
Dietary intake is an essential source of energy and nutrients, plays irreplaceable role in the breeding S. paramamosain seedlings. In this study, live Artemia nauplii (LA), compound feeds (CF), frozen copepods (FC) adult (FA) were utilized as feed during megalopa stage. To determine impact that diet has on metabolism crablets underwent metamorphosis from stage, analyses both metabolomics fatty acid content conducted. LC-MS-based analysis, a total 104, 205 83 significantly different...
A new method applying close range laser scan (Lidar) survey in capturing 3D objects was presented this study. One linear source Lidar used for the of objects. This approach is particularly essential modelling urban buildings a geospatial database. Data calibration and merging were conducted combing point cluster datasets surveyed from different locations angles one object order to generate data model entire object. The transformed converted into triangulated irregular network (TIN) mesh TIN...
The embryonic development of the oriental freshwater prawn Macrobrachium nipponense (De Haan, 1849) is described from observations on whole-mount embryos with nuclei stained using Sytox® Green. eggs are centrolecithal, non-polar, and oval-shaped, a diameter 300–500 µm. early cleavage pattern shows mixed modes. Notably, cells could shift to interior embryo form visual blastopore, which characteristic during gastrulation stage. putative intracellular body (ICB) be discriminated at...
This research investigated the distribution of eutrophication degree in Nansi Lake using remote sensing data. Nine sampling points were monitored with Chla, TP and TN three parameters upper lake Lake. TSI each was calculated Carlsonpsilas TSIM. Then linear model between data TSIM field monitoring built. The eutrophic state inversed, also assessed.
It is well known that mechanochemically activated phosphate rock (MAPR) could improve extractable phosphorus (P) (extracted in 2% citric acid) greatly an ecological way. To evaluate the agronomic effectiveness of MAPR, we conducted a field experiment using spring maize Luvisol (pH 6.47) soil Northeast China for three consecutive years. Treatments consist variation P levels substitution triple superphosphate (TSP) (100% TSP, 10% 20% 50% 100% MAPR). Compared with all combined applications MAPR...
The South-to-North Water Diversion project is a large water conservancy implemented by the Chinese government to solve shortage problem in North China, but oil slick pollution an important problem. Aiming at of pollution, control system collection device designed this paper. First all, design idea intercepting first, then collecting, and separating was determined, software programmed. simulation Proteus showed that program stable reliable, pressurizing could realize manual automatic...
Abstract Rainfall-induced landslides are a common geological hazard. Analyzing this problem necessitates the use of unsaturated soil theory, with soil-water characteristic curve (SWCC) being crucial component. Most existing seepage models established based on static model. However, dynamic capillary pressure has been observed in experiments conducted previous studies. In study, were performed to explore impact SWCC. The influence different infiltration rates was studied, and rate-dependent...
Abstract Hadal sediments are recognized as organic carbon depocenters with intensified microbial activity compared to adjacent abyssal sites due focusing of relatively labile materials. However, the sources and turnover hadopelagic its linkages activities have not been studied. We present first synergic research on particulate carbon, dark fixation, size‐fractionated community respiration proxy over Atacama Trench. The results demonstrate that all parameters attenuate rapidly from surface...
Methane hydrate is the vast potential resources of natural gas in permafrost and marine areas. Due to occurrence phase transition, dissociated into water absorbs lots heat. The incomprehensive knowledge endothermic reaction sediments still restricted production efficiency commercial development. This leads a complex thermal diffusion permafrost, which directly influences transition turn. In this research, heat during exploitation transferred two forms (specific latent heat). Besides, melting...
This research investigated the distribution of Chlorophyll-a and suspended substance (SS) in Nansi Lake using remote sensing data. The correlation between Landsat5 TM data field measurement for water quality was analyzed Pearson theory. inversion model SS as indexes were also established.
Abstract The mud crab Scylla paramamosain is one of the economically important aquaculture species in China. larval development characterized by two significant morphological changes, from 5 th zoea (Z5) to megalopa (M) stage and M first juvenile (C1) stage. In this study, we found that methyl farnesoate (MF) could prohibit Z5 metamorphosis a concentration-dependent manner, concentration 10 μ MF completely metamorphosis. Farnesoic acid (FA) also metamorphosis, but its effects seemed be...
This paper introduced fuzzy assessment of water quality based on membership grade by artificial neural network. Samples were obtained intensive interpolation standards, relative MG matrix was output as expectation value for network's train and application. Then, improved mathematics method applied to assess the Qingdao Dagu River.
